A Study Pertaining to the Role of Lexical Bundles in Academic English

本研究的目的是调查“词汇束”，特别是在学术英语领域。首先探讨了词汇束的概念，然后研究了一种从大规模语料库中检索词汇束的方法。然后，从学术英语语料库中检索了一些词汇束。在下一阶段，我们将词汇束的概念引入大学英语课堂，以确定加深对这一概念的理解是否有助于提高学生的写作技能。此外，还开发了一个从大型语料库中检索有用信息的计算机程序。

The purpose of this research was to investigate "lexical bundles" especially in the area of Academic English. First, the concept of "lexical bundle" itself was explored, after which a method for retrieving lexical bundles from huge-sized corpora was investigated. A number of lexical bundles were then retrieved from corpora of Academic English. For the next stage we introduced the concept of lexical bundles into university-level English classes to determine whether or not a deeper understanding of the concept would help students improve their writing skills. Furthermore, a computer program which retrieves useful information from huge-sized corpora was developed.
